Application October 23, 1953, Serial No. 387,834

Claims. (Cl. 43-424) The present invention relates to new and useful improvements in mole exterminators and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which is adapted to be expeditiously set substantially concentrically in the tunnel and which comprises novel means for wounding and disabling the animal as it attempts to pass therethrough in a manner to cause its subsequent death.

Another very important object of the invention is to provide a mole exterminator of the aforementioned character wherein conventional safety razor blades may be readily used for injuring or wounding the animal.

Other objects of the invention are to provide a mole exterminator of the character described which will be comparatively simple in construction, strong, durable, compact, reliable in use and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a perspective view, showing a mole exterminator constructed in accordance with the present invention in position for use.

Figure 2 is a view principally in side elevation of the device with portions broken away shown in section.

Figure 3 is a vertical sectional view, taken substantially on the line 33 of Figure 2.

Figure 4 is a perspective view of a pair of the blade reinforcing plates.

Figure 5 is a detail view in perspective of one of the arcuate blade spacing sleeves.

Figure 6 is an elevational view of the rod on which the blades, etc., are mounted.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a rod 10 of galvanized wire or other suitable metal. The rod 10 terminates, at one end, in a coil or loop 11. The rod 10 further includes threaded end portions 12 and 13. As shown in Figure 1 of the drawing, the coil 11 is adapted to be positioned substantially concentrically in a mole tunnel, as at 14.

Mounted on the coil 11 in a manner to extend longitudinally in the tunnel 14 is a plurality of spaced, radial conventional apertured safety razor blades 15. The blades 15 are firmly but removably secured in positionthrough the medium of rigid sleeves 16 and 16' between nuts 17 which are threaded on the end portions 12 and 13 of the rod 10 and the coil 11, respectively. It is to be noted that the sleeve 16 which encloses the rod 10 is relatively long and straight and that those which are mounted on the coil 11 are comparatively short and conform to the curvature of said coil.

Each of the blades 15 is provided on its sides with stiffening or reinforcing plates 18 of suitable metal. The reinforcing plates 18 are provided with openings 19 which accommodate the coil 11. The openings 19 are in registry with the usual central openings in the blades 15 through which the coil 11 passes. The plates 18 further 2,725,662 Patented Dec. 6, 1955 include, on one end, tapered, bendable tongues 20 which are inserted through the usual end openings 21 in the blades 15 and clinched over the adjacent end portions of the plates on the opposite sides of said blades. As seen in Figure 2 of the drawing, the reinforcing plates 18 are also engaged between the ends of the spacing sleeves l6 and 16. a

It is believed that the manner in which the device is used will be readily apparent from a consideration of the foregoing. Briefly, the necessary excavation is made in the ground, as at 22, to permit the coil 11 to be positioned in the tunnel 14 with the rod 10 rising therefrom and extending above the surface of the ground. The excavation is then refilled and smoothed over. The mole traveling in the tunnel 14 pushes through any obstruction formed by the refill and attempts to pass through the coil 11 and is cut in one or more places by the blades 15. Being thus injured, the mole may bleed to death or if the front feet of the animal are cut it will be unable to continue and may starve to death. By simply loosening either or both of the nuts 17, the blades 15 may be readily adjusted, reversed orv removed for replacement.

Although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A mole exterminator comprising: a rod, a coil on one end of said rod adapted to be positioned substantially concentrically in a mole tunnel, and a multiplicity of spaced, elongated apertured blades mounted on the coil and adapted to extend, longitudinally in the tunnel,

said coil passing through the apertures in said blades.

2. A mole exterminator comprising: a rod, a loop on one end of the rod adapted to be positioned substantially concentrically in a mole tunnel for the passage of a mole therethrough, a multiplicity of blades mounted on said loop, and spacing sleeves on the loop between the blades.

3. A mole exterminator comprising: a rod, a coil on one end of said rod adapted to be positioned substantially concentrically in a mole tunnel for the passage of a mole therethrough, a multiplicity of blades mounted on said coil, spacing sleeves between the blades, and nuts threaded on the free end portions of the rod and the coil for clamping the blades between the sleeves.

4. A mole exterminator comprising: a loop adapted to be mounted substantially concentrically in a mole tunnel, a multiplicity of blades mounted at spaced points on the loop, said blades being elongated and having centrally located openings therein accommodating the loop and further having openings in their end portions, reinforcing plates mounted on opposite sides of the blades and having openings therein for the passage of the loop, bendable tongues on the plates extending through the end openings in theblades and engaged over the adjacent end portions of the plates on the opposite sides of said blades, and means for securing the blades in position on the loop.

5. A mole exterminator comprising: a rod, a coil on one end of the rod, sleeves mounted on the rod and the coil, blades mounted on the coil and the rod between the sleeves, and nuts threaded on the rod and the coil for clamping the blades between the sleeves.
